How is CBD oil made?

There are many methods of extracting and making CBD oil, including the CO2, ethanol, liquid solvent, and oil infusion extraction methods being the commonest. Since the resultant oil might still have some impurities, reputable brands subject it to distillation, a secondary process that purifies the oil further.

CBD is sold as a supplement and makes a great additive to tinctures, oils, gummies, mints, lozenges, chocolates, drinks, and other baked products.Since the Farm Bill was passed in 2018 to make CBD federally legal, many states have dedicated CBD shops and stores that sell CBD oil products and accessories, although you can buy these in health food stores. Still, remember that the Farm Bill granted the states the mandate to amend their CBD laws, and some states still regard the cannabinoid as illegal. Do you know how your favorite CBD oil is made? Peer into this article to appreciate the process of manufacturing CBD oil.


The Basics About CBD Oil

Also called cannabidiol, CBD is a cannabis extract removed from hemp or marijuana plants. The two are sativa strains; only hemp plants have less than 0.3% THC, while marijuana plants harbor higher THC percentages. Because of the lower THC concentrations, CBD is non-psychoactive, meaning you cannot get 'high' from taking CBD oil. Whether you want CBD topicals, edibles, vapes, capsules, or tinctures, you can have them in one or more of the following CBD formulations;


Full-spectrum CBD

It is also called whole-plant hemp CBD oil, boasts multiple cannabinoids, terpenes, THC, and flavonoids, and has a full entourage effect because of the man compounds.


Broad-spectrum CBD Oil

This formulation is more like full-spectrum CBD oil in composition and is also linked to a full entourage effect but lacks the psychoactive THC.


Isolate-based THC

This is pure CBD without additional cannabinoids, terpenes, and flavonoids and is not linked to a full entourage effect because of the limited compounds.


How Is CBD Oil Made?

The process starts with extracting the oil from the hemp extracts, after which purification and 3rd party quality tests follow to confirm that the final products are safe for human consumption. There are many CBD extraction methods, and they all vary in safety and efficiency. Below are the commonest methods employed in stripping CBD oil from the hemp surfaces.


CO2 Extraction

The CO2 extraction method is one of the most effective and safest extraction techniques in the hemp arena. It involves passing the dried or decarboxylated hemp flowers through CO2 to strip off CBD. There are three chambers, and the first one carries solid CO2. The hemp flowers are passed through this chamber and moved to the second chamber with semi-liquid CO2. The extract is again passed through this chamber before it can be moved to a third chamber with CO2 in gaseous form. The final chamber, having gaseous contents, allows the extract to settle as the gas moves to the next stage. The method is the gold standard in the industry since it is safe and less likely to attach solvents to the extracts and contaminate them. There is a possibility of erring and attaching the gas in liquid form to the extracts, but reputable brands that have established themselves well opt for the supercritical CO2 extraction method, which is more efficient. Still, CO2 extraction requires massive investment in the workforce and machinery for the chambers.


Ethanol Extraction

In this case, food-grade alcohol (ethanol) is used to remove CBD from decarboxylated hemp flowers. The flowers are passed through the ethanol as and CBD is removed. Ethanol extraction is mainly used for CBD oil that will be put in vape pens, tanks, and cartridges, although some brands have it as their signature extraction method. Many CBD manufacturers appreciate and use ethanol to extract CBD because it is more time-efficient and you need not waste time as with the CO2 extraction method. Besides, ethanol extraction seems fairly safe, cost-effective, and efficient. Still, eh method may accidentally and unnecessarily attach volatile solvents to the extracts, making them unsafe for consumption.


Liquid Extraction

Ethanol and CO2 extraction methods are not all there is for stripping CBD oil from hemp surfaces. You can equally remove CBD oil from hemp using liquids like isopropyl alcohol, butane, and hexane. While there are many options from which you can choose, liquid extraction comes with its fair share of drawbacks, the primary one being the attachment of the liquids to the extract and compromising the quality of the resultant oil. Besides, some liquids do not remove all impurities and crash chlorophyll in the extracts, making them binge green and bitter.


Oil Infusion

You can extract CBD oil from hemp flowers using oil infusion. Hemp flowers need to be decarboxylated by heating them to 100 degrees Celsius. You can use olive or MCT coconut oil for oil infusion.


Conclusion

CBD oil is made by extracting hemp using the oil's appropriate technique to further purification to remove traces of impurities. There are many extraction methods, with CO2, ethanol, oil infusion, and liquid solvent extraction methods. These methods vary in safety, efficiency, and cost-effectiveness. Most ‘boutique’ CBD brands opt for further purification to clear contaminants in the extracts.
